NICHOLAS G. ORRIGK, OF CANTON, MISSISSIPPI.

PLOW.

SPECIFICATION forming part of Letters Patent No. 233,795, dated October 26, 1880.

Application filed July 14, 1880. (N0 model.)

To all whom it may concern:

Be it known that I, NICHOLAS O. ORRIOK, of Canton, in the county of Madison and State of Mississippi, have invented certain new and useful Improvements in Plows and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to plows; and it consists in certain improvements in the construction and arrangement of the landside, the heel of which is made adjustable, so as to enable the suck to be regulated and maintained as the point wears away, substantially as will be hereinafter more fully shown and described with reference to the drawings, in which Figure l is a perspective view. Fig. 2 is a side view. Fig. 3 is a detail "iew of the heel of the landside, and Fig. 4 is a detail view of the head of the adjustable brace and themeans for securing the same.

Corresponding parts in the several figures are denoted by like letters of reference.

In the drawings hereto annexed, A represents the plow-standard, which is constructed and hinged to the beam in the manner shown in the patent granted to me on the 15th day of June 1880, No. 228,835.

B is a brace, pivoted between the parts or side pieces of which said standard is composed, near the center, and extending up and down in a rearward direction.

The upper end, C, of brace B is provided with a convex notched plate, D, having a perforation to receive a bolt, E, adjusted between two concave notched flanges, F 13, upon the under side of the rear end of the beam.

It will be seen that by tightening the nut G upon the bolt the notched plate is forced up toward the notched flanges, thus securely retaining the standard and brace in any position to which they may have been previously adjusted in relation to the beam.

The point H and mold-board I of the plow are secured, in any suitable manner, to the foot of the standard.

- J is the landside, the rear end of which is provided with a segmental recess, K, to re ceive the heel L, which is pivoted upon a bolt, M. The rear end of the heel L is provided with a bolt, N, adjustable in a segmental recess, 0, in the lower end of brace B, as shown.

The lower edge of the heel-plate is provided with laterally -projecting flanges, P P, which serve to guide it in the ground and insure the necessary suck to keep it in position.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of my invention will be readily understood.

By adjusting the heel-plate, wear upon the point of the plow may be compensated for, so as to cause it always to run ei'enly and smoothly.

Havingthus described my invention, I claim and desire to secure by Letters Patent of the United States- The combination of the standard A, pivoted brace B, having convex notched plate D,

notched concave flanges F, secured upon the my own I have hereto affixed my signature in presence of two witnesses.

NICHOLAS OROMWELL ORRIGK.
